IMPROVEMENT IN HARRows.

The Schedule referred to in these Letters Patent and making part.' ofthe same.

My invention consists, first, in constructing a har-.

row in. four or'more sections, and so hanging said sections`v togetherthat the barrow will conform itself to any unevenn'ess of the groundover which it is passing,-y;yielding thereto both longitudinally andtransly,`and so that the principal sections can rise or each other; and

It consists, secondly, in so arranging the draft of the barrow dividedinto sections, longitudinally, said lateral sections being unconnected,except by a single hinge-jointin front, that the draft will prevent thespreading apart, as hereinafter described.

In the accompanying drawing- Figure 1 represents a plan or top view of abarrow made in pursuance of my invention; and

Figure 2 represents a side view of the saine.

The harrow is divided, longitudinally, into two sections, A and A', andthese sections are hinged together at a, but unconnected at all otherpoints.

lhe said sections A and A are divided, trans- Aversely, into two or moresections, B B', C C', and

The front sections B and B consist, each, of two tooth-bars, rigidlyattached together bycross-bars b.

The sections O and C consist, each,in like magner, of two tooth-bars,which are also rigidly attached together by cross-bars c, `and the saidsections C and O' are attached to the said sections B and B by flexiblehinged connections b. rlhe said sections B and B' and C and C' may eachor either of them. consist of .three or more tooth-bars, rigidlytttachetltogether, if

desired.

The sections D and D' are attached to the sections 0 and Cby hooks andeyes, at (l d, or by any other suitable hinged and flexible connection,easily attachable and detacha'ble,so that said sections may be readilyattached to or detached from the barrow, to increase or diminishitslength. lThese sections may also each consist of two or moretooth-bars, rigidly attached together, if deemed expedient; andaddiconnteracted by thc drag of the said sections C and C in the rear.These connections are also made in the form of hooks and eyes, and aredetachable for the purpose of more conveniently transporting or storingthe barrow.

The hooks are provided with springs, t', like an or dinary snap-hook, toprevent accidental detachment in working. I do not, however, limitmyself to this particular form of hinged connection, as any detachableand exible joint will answer the purpose.

' lThe sections C and D and O and D are provided with handles I t andh', for the purpose of lifting them .to pass over obstructions, or ofclearing the teeth of any clogging matter.

The sections D anti Dare attached to the said handles by slack chains orcords, j, to prevent said sections from lopping down when the handlesare raised.

rIhe draft is from three rods, c and e', linked or hooked to the frontcorners, and j, to the center of the harrow,and all connecting in acommon ring or link, E.

rIhe central rod f links to the central hingeljoint a, and,consequently, tlie'ceut'ral draft is equal' upon the inner front cornersof the main sections A and A', and this electually prevents the saidseetiou'sfrom spreading apart through the center, though whollyunconnected except by the hinge-joint a in front.

It will be seen that the sections C and C are not immediately connectedtogether, being onlyconnected remotely, by means of the hinged joint a,and so either of said sections can rise orbe lifted, to pass over anobstruction,independently of the other. The same is true in4 respect tothe detachable sectionsD and D', or any additional detachable sectionsthat may be provided. A

Having thus fully described my invention and its mode of operation, I donot claim a harrow made in sections and hinged together longitudinallyor transversely, or both; but

W'hat I do claim as my invention, and desire to se-r cure by LettersPatent, is

1. A barrow. divided into sections longitudinally and transversely, antisaid sections so united by hinged j connections that they wiltyield toany nnevenness of the ground independently of each other, and so that,through the center, longitudinally, said sections will be whollyunconnected except bya single hinged joint in front, substantially asdescribed.

2. In combination with a barrow divided longituldinally into hingedsections, a draft from the center and the two forward corners,substantially as and for the purpose described. l
